我在下面有此Python代码。下面是我尝试将其转换为MATLAB代码的尝试。我是import java.util.Scanner;
import java.util.Queue;
import java.util.LinkedList;
public class BinarySearchTree<T extends java.lang.Comparable<? super T>>
{
private static class BinaryNode<T>
{
private T element; // The data in the node
private BinaryNode<T> left; // Left child
private BinaryNode<T> right; // Right child
// Constructors
BinaryNode( T theElement )
{
this( theElement, null, null );
}
BinaryNode( T theElement, BinaryNode<T> lt, BinaryNode<T> rt )
{
element = theElement;
left = lt;
right = rt;
}
}
private BinaryNode<T> root; //root node of the tree
// Constructor
public BinarySearchTree( )
{
root = null;
}

return t;
return findMin( t.left );
}

{

}
else if( compareResult > 0 )
{
t.right = insert( x, t.right );
}
else

return t;
}

}
的新手，我正在练习进行转换。 classdef的问题（想计算我调用构造函数的次数），并且希望得到有关如何纠正转换的反馈。
Python版本：
counter我尝试进行MATLAB转换：
class Test:
counter = 0
def __init__(self, id):
self.id = id
Test.counter += 1
答案 0 :(得分：0)
我找到了解决方案
classdef Test
properties
id;
end
methods
function self= Test(id)
self.id = id;
end
end
methods (Static)
function c= counter
persistent Count;
if isempty(Count)
Count = 1;
else
Count = Count + 1;
end
c = Count;
end
end
end
